حلقات O من Aflas بقطر مقطع 0.103 بوصة × قطر داخلي 0.611 بوصة | AS568-114 | داش 114 | صلابة 80 (50/عبوة)

These fit perfectly on the valve stems in our high-temp steam lines, and the 80 durometer feels noticeably firmer than the generic ones I used before. The -10°F to +450°F range gives me confidence they'll hold up where standard Buna-N would fail.

Just installed a set of these Aflas o-rings on a high-temp manifold and they're holding up great under the 400°F range; the 80 durometer feels solid without being too stiff. The 0.611" inner diameter fit perfectly on my application, and the package of 50 should last me quite a while.

Finally got a chance to use these on a high-temp pneumatic line, and the 450°F rating is spot on—no degradation after a full shift. The 0.103" cross-section gives a nice, snug seal that’s easy to seat.
